1. Disconnect the negative battery lead.

2. Let the vehicle stand for at least an hour. LONGER if need be. The motor must be cool to the touch.

3. Once cool, reconnect the battery lead, close the hood, and start the vehicle. DO NOT touch the gas at all!

4. When the car has reached operating temperature, or the cooling fan has gone on and off once, shut off the car.

5. Turn the vehicle back on and go for a drive based on what you want the car to do. Want every bit of horse power? Take 1st and 2nd gear to red-line a few times. Want to teach the computer that your just a commuter? Drive nice in some various traffic conditions for about 20 minutes. Then go home and shut the car off.

6. After that? Drive the car like normal, you've paved the way for what you'd like the computer to aggressively try and learn. It will take a few tanks of gas before the computer will be "tweaked" for one manner of driving or another. The first tank may also show a drop in MPG around town, that will go away soon enough.
